	The code on the "gobject-adaptor" branch of ORBit2 might be interesting
here to give you an idea how to implement it. Without thinking about it
too hard, you need:
 + An object adaptor to handle incoming requests, look up the GObject 
 associated with and object reference and invoke the method or 
 whatever using the introspection data.
 + Some code to generate a CORBA object reference on request for a 
 GObject.
 + Define a GObject CORBA interface which would include a method for 
 querying the introspection data. All GObjects would implicitly 
 expose this interface. We might want to include ref-counting or 
 leasing in that interface.
	Actually, this would all work quite well I think :-)
Cheers,
Mark.
